Hi: I'm new to ROS system, and i have a problem when using the libuvc_camera package; below are my steps:

Firstly, clone the libuvc_camera from https://github.com/ktossell/libuvc_ros
commands in the consol : cd libuvc_camera ; mkdir build; cd build; cmake .. ; make ; sudo make install
commands: source devel/setup.bash
then if i run the command: rosrun libuvc_camera camera_node; it display messages : couldn't found executable file camera_node in libuvc_camera ; found libuvc_camera/build/devel/lib/libuvc_camera/camera_node but it is not a executable file;
and when i use the tab; it display commands: rosrun libuvc_camera UVCCamera.cfg
can somebody tell me what is the problem ? thanks!

I guess you should have done more like:

create the workspace folder
create src folder inside workspace
clone into src folder
execute catkin_make in workspace folder

and before the last one you could install the needed dependencies as seen here: http://answers.ros.org/question/75241...

Btw you should also be able to install it by package manager I guess it should be just sudo apt-get install ros-indigo-libuvc-camera

Thanks very much; i have done what you suggest; and the workspace build successfully. Now i want to run the camera_node in the libuvc_camera package, and manual its focus absolute; Can you please give me some more suggestions? Thanks so much!

I guess you should create a new question for that. Cause having an error and making it run and specific settings are completely different things.
